A fisherman in a row boat notices that one wave crest passes his fishing line every 5 seconds. he estimated the distance between the crests to be 1.5 meters and estimates that the crests of the waves are 0.5 meters above the troughs. Using the data find the frequency of the wave divide how many wave crests pass every 5 seconds

Agraduated cylinder contains 63.0 ml of water. a piece of gold, which has a density of 19.3 g/ cm3, is added to the water and the volume goes up to 64.5 ml. calculate the mass in grams of the gold that was added to the water. explain how you got your answer.

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
